Prometheus

Prometheus

The little moon Prometheus is featured in this image is creating channels (gores) and streamers in the F ring of Saturn. Prometheus and Pandora are believed to be responsible for much of the structure of the ring. Can’t see the moon? Look at the speck at about 10 O’clock.

Prometheus is only 86 km (53 miles) across and has an orbit that regularly brings it to the F ring. When the encounter occurs as we can see the gores where it enters and streamers pulled away in its wake as it exits.
